Abstract: Improved methods and apparatus for telecommunications call service and call feature processing utilize a compiled representation of a textual description in a mark-up language of operations describing a telecommunication service is generated. Objects access this compiled representation, in response to events occurring with respect to a telecommunication service, in order to cause operations represented in the compiled representation to be executed.

Abstract: Improved systems and methods for call and call feature setup, administration and processing on PSTN and other telecommunications networks are provided. Calls are set up on a service plane of a conceptual switch that includes a switch plane, control plane, and service plane that are analogous to the OSI layered model of networks including a physical layer, network layer and application layer. Call set-up logic is separated from the switching fabric, allowing for flexible, on-demand, modification of service options using software while maintaining the same switching fabric in hardware. Call set-up is accomplished by a call request made upon connection of a call to the switch. This causes a call agent to search an eXtensible Markup Language knowledge base to find a web page corresponding to the initiating caller. The Web page may be collocated with the switch or on a LAN with the switch or on the “Web,” even on the caller's termination equipment (telephone).

Abstract: The present invention relates to methods and system for providing telecommunications services, such as call waiting, three-way call, and automatic recall, utilizing a plurality of state machines. Logic specifications define a set of states for each state machine. Each state in turn defines at least one action to be performed in response to a signal received by the state machine. The logic specification for each state machine can be stored, for example, in a textual format in a mark up language, such as HTML, XML, or or other markup language. A compiled representation of the logic specification is generated. Further, a context object tracks a current state of the telecommunication service. The context object accesses the compiled representation in response to an event, e.g., a call progress event, in order to effect a state transition and/or perform an action with respect to the telecommunication service.
